Description
The Victron MultiPlus-II 48/5000/70 is a 230 V multifunctional inverter/charger for professional marine, vehicle and off-grid systems built around a 48 V battery bank. It combines a strong 5000 VA pure sine wave inverter with a 70 A battery charger in a single enclosure, supplying clean 230 VAC mains power from the batteries. The 48 V architecture keeps DC currents low, simplifying cabling on larger installations.
PowerAssist is the standout capability. When shore or generator power is limited, the MultiPlus-II adds energy from the battery to cover load peaks, preventing the source from overloading while still using any spare capacity to recharge. The integrated transfer switch returns loads to the inverter in under 20 milliseconds during a grid failure, so sensitive electronics keep running without disruption.
Designed for energy storage and solar self-consumption, the MultiPlus-II works with both MPPT solar chargers and grid-tie inverters, has built-in anti-islanding and a long list of grid-code approvals, and can be paralleled or three-phased for higher output. An external current sensor extends PowerControl and PowerAssist up to 100 A. Setup, monitoring and control run through VictronConnect, a GX device and the free VRM portal.
